{
  "summary": "Reviewed `aws-lc/ssl/s3_pkt.cc`, which implements TLS record write/read paths, alert dispatch, and ChangeCipherSpec handling. I checked for install-time execution, network/exfiltration, credential or secret access, dynamic code loading, obfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/include/openssl/dh.h`, a public Diffie-Hellman API header that only declares constants and function prototypes for key generation, parameter parsing, and key agreement. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise in this target file.\nReviewed `aws-lc/crypto/decrepit/cast/cast.c`, which is a straight CAST5 block-cipher implementation with ECB/CBC helpers and EVP registration. I did not find any concrete supply-chain or malicious indicators in this file: there are no install hooks, network/exfiltration paths, dynamic code loading, obfuscation/deobfuscation, secret harvesting, or persistence behavior.",
